In a manner relating to or affecting the sense of taste.
From 'gustatorial' (relating to taste) plus the English adverbial suffix '-ly,' ultimately from Latin 'gustare' (to taste). A rare formation in modern English.
This word is so rare that even spell-checkers often flag it, showing how English prefers simpler words—most people would just say 'in terms of taste' rather than using 'gustatorially,' even though the word is technically correct.
